Difference between Field Symbol and Field Group in SAP ABAP Programming

In SAP ABAP programming, the main difference between a field symbol and a field group lies in their functionality and usage.

Field Symbol: A field symbol in ABAP is a placeholder or a pointer that does not have a fixed data type at the time of declaration. It is dynamic and can be assigned to any data object during runtime, allowing for flexibility in processing various data types. Field symbols are commonly used for referencing data objects dynamically in programs.

Field Group: On the other hand, a field group in ABAP is used to group together multiple field names related to a specific database table or structure. Field groups are defined in the ABAP Dictionary and are primarily used for data selection and reporting purposes. They allow developers to organize fields logically and retrieve specific sets of data efficiently.

Overall, while field symbols provide flexibility in referencing data dynamically, field groups offer a structured way to group related fields for better data management and retrieval in SAP ABAP programming.
